Parameters

Primary Axis: Axis along which the individual elements are aligned for 1D linear probe
Secondary Axis / Elevation(Y): Axis perpendicular to the primary axis of a probe
Number of Elements (Primary Axis/n): Total number of elements aligned along the primary axis
Number of Elements (Secondary Axis/m): Total number of elements aligned along the secondary axis (Matrix Array only)
Primary Axis Pitch(P/Px): Center-to-center distance between two consecutive elements along the primary axis
Secondary Axis Pitch(PY): Center-to-center distance between two consecutive elements along the secondary axis (2D Matrix Array only)
Primary Axis Aperture(A/Ax): Dimension of the probe surface along the primary axis
Ax = (n–1) • Px + Ex
Secondary Axis Aperture(AY/Wpassive): Dimension of the probe surface along the secondary axis
Ay = (m–1) • Py + Ey
